Circulation: The liver is essential for protein synthesis and the regulation of portal vein pressure. Its alterations directly affect the veins of the legs.
Metabolism: The liver produces proteins that keep fluid within the blood vessels. If these proteins are lacking, fluids leak into the tissues.
Detoxification: Toxins accumulated due to liver dysfunction can cause skin reactions.
Warning signs in the legs that suggest liver problems:
1. Swelling (in thighs and feet)
What it looks like: shoes feel tight, sock marks persist; pressing with a finger leaves an indentation that slowly disappears. It usually worsens at night.
Relationship to the liver: a damaged liver produces less albumin, a protein that retains fluid within the blood vessels. Its deficiency causes edema. In addition, portal hypertension disrupts normal venous flow.
2. Vascular “stars” (telangiectasias)
What they look like: small red or purple “spiderwebs” on ankles and feet.
Relationship to the liver: common in chronic diseases such as cirrhosis. They are due to alterations in hormone metabolism (especially estrogen) and increased pressure in the veins.
3. Change in skin color
What it looks like: a yellowish tone (mild jaundice) or darker areas (hyperpigmentation), especially around the ankles.
Relationship to the liver: jaundice indicates problems in the breakdown and elimination of bilirubin; hyperpigmentation reflects metabolic disturbances and melanin accumulation.
